<h3>Answer:  175 square cm</h3>

Work Shown:

Area of square = side*side = 7*7 = 49

Area of one triangle = (1/2)*base*height = (1/2)*7*9 = 31.5

Area of four triangles = 4*(area of one triangle) = 4*31.5 = 126

total area = (area of square)+(area of four triangles) = 49+126 = 175

This total area of the net is the same as the surface area of the square prism. Imagine folding this 2D flat shape to form a 3D figure.

A meteorologist reports that there is a 30% chance the temperature will fall below freezing tomorrow. On any given day, the bus
sladkih [1.3K]
<h3>Answer:  18%</h3>

===========================================================

Explanation:

Convert each percentage to decimal form

  • 30% converts to 0.30
  • 60% converts to 0.60

Then multiply the decimal values

0.30*0.60 = 0.18

That converts to 18%

So there's an 18% chance that both events happen at the same time. In other words, there's an 18% chance of the temperature falling below zero and the bus being late.

the straight line L has the equation 4y=5x+3. Point A has the coordinates (3,-2) Find the equation of the line straight line tha
Aleonysh [2.5K]

Answer:

y = - \frac{4}{5} x + \frac{2}{5}

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Rearrange 4y = 5x + 3 into this form by dividing the 3 terms by 4

y = \frac{5}{4} x + \frac{3}{4} ← in slope- intercept form

with slope m = \frac{5}{4}

Given a line with slope m then the slope of a line perpendicular to it is

m_{perpendicular} = - \frac{1}{m} = - \frac{1}{\frac{5}{4} } = - \frac{4}{5} , thus

y = - \frac{4}{5} x + c ← is the partial equation

To find c substitute (3, - 2) into the partial equation

- 2 = - \frac{12}{5} + c ⇒ c = - 2 + \frac{12}{5} = \frac{2}{5}

y = - \frac{4}{5} x + \frac{2}{5} ← equation of perpendicular line

Samuel can type nearly 40 words per minute. Use this information to find the number of hours it would take him to type 2.2 × 105
Dafna1 [17]
I believe the answer is .09625 hours

Explanation: first you do 2.2 x 105= 231
Then you do 231/40=5.775 to get how many minutes it takes to type 231 words. Then u divide 5.775/60 to get how many hours it would take.
